I cannot seem to solve it either.

I have it as well. It is a pos coin, so maybe I misconfigured something.

OK. So for me the problem was I had to change in the settings.json file the "getnetworkhashps" command in the "nethash" line for "netmhashps" as it was a Hybrid PoW/PoS coin I was dealing with.
The line corrected would look:
"nethash": "netmhashps"
I hope my case can be helpful for someone else.
